[QUOTE="MacInWin, post: 1919446, member: 396914"] Calibrating the battery is hard on it. But if you only do it once, the torture won't have a lot of impact. The ONLY reason to calibrate a lithium battery is to allow the Mac to be able to have a more accurate estimate of power remaining. It does nothing FOR the battery itself, and is, in fact, hard on it because lithium batteries do not "like" being driven all the way down. Try to keep it in the 50-80% range and it should last a long time. [/QUOTE]
